Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a seal peeling device that peels a seal that is easily broken when a bending force is applied to the seal from a mount.
[0002]
[Prior art]
As shown in FIG. 4, the conventional seal peeling apparatus peels off the seal B from the mount A by bending the mount A at an acute angle with the knife edge 4 a of the peeling section 4 and moving the same, and as shown in FIG. stopping the movement of the mount a in a state where part B ₁ of the end of the seal B is stuck to the mount a, suction-holding the seal B by the transport unit 5, then its retention as shown in FIG. 4 (b) The seal B was peeled off from the backing sheet A by peeling off the sticker B and the backing sheet A by the movement of the transport section 5.
[0003]
However, if the seal B, which is easily broken or broken, such as a falsification prevention seal, is pulled while the seal is stuck to the mount A as shown in FIG. There was a problem that it was damaged and could not be used.
[0004]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a seal peeling device that can be easily peeled off from a backing sheet without breaking a fragile seal such as a tamper-proof seal and the like. It is to provide.
[0005]
[Means for Solving the Problems]
The present invention provides, as means for solving the above problems, a seal peeling device described in each claim of the claims.
The seal peeling device according to claim 1, wherein a peeling part for peeling the seal from the mount is reciprocally movable, and a first and a second clamp unit for clamping the mount on the upstream side and the downstream side of the peeling part, respectively. A tension portion is provided between both clamp portions, the mount is clamped by both clamp portions, the peeling portion is moved while holding the seal in the transport portion, and a predetermined tension is applied to the mount, and the seal is peeled from the mount. It is like that. With this, while the seal is held, the mount is pulled with a predetermined tension at the tension portion and the peeling portion moves, so that the mount on which the seal is pasted is peeled off and removed from the seal pasting surface, Since the backing sheet can be peeled off little by little without applying a bending force to the seal, breakage of the seal can be prevented.
[0006]
According to the second aspect of the present invention, the seal is positioned at the end of the peeling part, and the peeling part is moved at least by the length of the seal, whereby the seal can be completely peeled from the backing sheet. Since the seal can be held by the transport unit, the seal does not fall even when the seal is completely peeled off from the backing sheet.
According to a third aspect of the present invention, there is provided a seal peeling device, wherein the tension portion is arranged between the peeling portion and the second clamp portion, and is constituted by a dancer roll stretched by a mount and vertically moved up and down. A predetermined tension corresponding to its own weight can be easily applied to the mount.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a seal peeling device according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the entire configuration of the seal peeling device of the present invention. The seal peeling device 1 mainly includes a feeding unit 2 for feeding out a tape-shaped mount A to which a seal B is attached, a peeling unit 4 for peeling the seal B from the mount A, and a transport unit for holding and transporting the peeled seal. 5 and a winding section 3 for winding the mount A from which the seal B has been peeled off.
[0008]
The delivery unit 2 has a reel structure, and the empty old reel from which all the mounts A have been sent out can be replaced with a new reel on which the mount A to which the seal B is attached is wound. I have. Similarly, the take-up unit 3 also has a reel structure, and the old reel that has taken up the mount A from which the seal B has been peeled off can be replaced with an empty new reel. The mount A is moved by rotating the winding unit 3.
[0009]
As shown in FIG. 2, the tip of the peeling section 4 is a knife edge 4 a, and the peeling section 4 can be reciprocated by the driving section 8. The mechanism of the drive unit 8 employs a fluid pressure driven piston-cylinder mechanism in FIG. 2, but any other known reciprocating mechanism can be appropriately employed.
[0010]
The transport section 5 has a suction head 5a connected to a vacuum source (not shown), and the seal B peeled off from the mount A is vacuum-adsorbed and transported by the vacuum head 5a.
On the upstream side of the peeling section 4, a first clamp section 6A for holding the mount A to stop the movement of the mount A is provided, and a second clamp section 6B is also provided downstream of the peeling section 4. . As shown in FIG. 3, these clamp portions 6A and 6B fix the mount A by moving the clamp member 61 and pressing the mount A against the fixing surface 62, and moving the clamp member 61 to press the mount A. Is released to release the mount A.
[0011]
Between the first and second clamp portions 6A and 6B, and between the peeling portion 4 and the second clamp portion 6B, there is provided a tension portion 7 for applying tension to the mount A between the clamp portions. The tension portion 7 is composed of two guide rollers 71A and 71B for guiding the mount A, and a dancer roll 72 between the guide rolls and on which the mount A is stretched. The dancer roll 72 is in a free state, and tensions the mount A by moving up and down. Although the tension is applied to the dancer roll 72 by its own weight, the tension applied to the mount A can be adjusted by urging the dancer roll 72 with a weight or a spring.
[0012]
Next, the operation of the seal peeling device of the present invention configured as described above will be described with reference to FIGS. First, the feeding section 2 which is a reel on which the mount A to which the seal B is affixed is wound is mounted on the apparatus, and the mount A is pulled out from the apparatus, passed through the first clamp section 6A, and is placed on the surface of the peeling section 4. Then, it is bent to the back side of the peeling part 4 by the knife edge 4a at the tip. From there, the mount A is passed through the tension unit 7, and the mount A is wound on the reel of the winding unit 3 through the second clamp unit 6B.
[0013]
The seal B attached to the mount A is firmly attached to the mount A up to the knife edge 4a of the peeling portion 4. When the seal B affixed to the mount A is positioned near the knife edge 4a, the winding and feeding of the mount A are stopped, the first and second clamps 6A and 6B are operated to close the clamp member 61, and the mount A is closed. Is clamped. In this state, the suction head 5a of the transport section 5 comes into contact with the seal B on the peeling section 4, and sucks and holds the seal B attached to the mount.
[0014]
Next, as shown in FIG. 3, while pulling the mount A by the dancer roll 72 of the tension unit 7, the drive unit 8 is operated to move the peeling unit 4 backward, and the knife edge 4 a is moved from under the seal B. Then, the mount A is removed from under the seal B. The seal A is easily peeled off from the mount A by the base material A being largely bent by the knife edge 4a. When the knife edge 4a is completely moved from below the seal B, the seal B is completely peeled off from the backing sheet A and is also suction-held by the suction head 5a. This series of operations is shown in FIG. The seal B, which is completely peeled off from the backing sheet A and held by suction on the suction head 5a of the transport unit 5, is transported by the transport unit 5 so as to be affixed to a required location of the product.
In this manner, the backing sheet A is folded and the sticker B and the backing sheet A are completely peeled off while the sticker B is being sucked and held, so that even the easily tamper-proof seal can be peeled off from the backing sheet A without being damaged. it can.
[0015]
As described above, in the present invention, the peeling portion is made movable, and both sides of the mount hung on the knife edge of the peeling portion are fixed and openable clamp portions are provided. By providing the tension portion so as to be pulled with a predetermined tension, even a fragile seal such as a tamper-proof seal or the like can be reliably peeled off from the backing paper without being broken.
